The stacking mechanism of the 1H-4H proton transfer in 4-pyridone, 4-pyridinthione and p-aminopyridineare constructed. For quantitative description of this process by means of the quamtumchemicalmethod density functional theory (DFT) the activation energy (

Bilayer graphene possesses two degenerate lowest energy configurations which are geometrically mirrored—AB and BA stacking[1]. Both stacking geometries have been observed as domains in bilayer systems grown by chemical vapor deposition[2]. Here we examine the structure at the interfaces of stacking domains using atomic-resolution scanning transmission electron microscopy (STEM) and standard dar...

The interfacial energies of twin boundaries and stacking faults in metal magnesium have been calculated using first-principles supercell approach. Four types of twin boundaries and two types of stacking faults are investigated, namely, those due to the (1011) mirror reflection, the (1011) mirror glide, the (1012) mirror reflection, the (1012) mirror glide, the I1 stacking fault, and I2 stacking...

Stacking fault formation during epitaxial SiGe layer growth in bipolar complementary metal oxide semiconductor (BiCMOS) process which caused high yield loss due to its leakage current on bipolar transistors has been studied. Through the analysis of process flow, oxidation induced stacking faults were indicated as a possible root cause of the yield loss. The identification of the oxidation induc...

Starting from a semi-empirical potential designed for Cu, we have developed a series of potentials that provide essentially constant values of all significant (calculated) materials properties except for the intrinsic stacking fault energy, which varies over a range that encompasses the lowest and highest values observed in nature. These potentials were employed in molecular dynamics (MD) simul...

Variable temperature scanning tunneling microscopy experiments reveal that in Ir(111) homoepitaxy islands nucleate and grow both in the regular fcc stacking and in the faulted hcp stacking. Analysis of this effect in dependence on deposition temperature leads to an atomistic model of stacking-fault formation: The large, metastable stacking-fault islands grow by sufficiently fast addition of ada...

Automatic equipment for cigarette sorting and stacking is applied to a recycling process of tobacco in cigarette factory. It takes the place of manual work, such as sorting and stacking cigarettes to transfer boxes. The equipment realizes the functions such as orientation, sorting, steering, and stacking of the cigarettes in proper order. Omron CP1H type PLC is selected as the control center of...

This paper provides a three-step framework to predict user assessment of the suitability of movies for an inflight viewing context. For this, we employed classifier stacking strategies. First of all, using the different modalities of training data, twenty-one classifiers were trained together with a feature selection algorithm. Final predictions were then obtained by applying three classifier s...

We present an analysis of a general machine learning technique called ‘stacking’ for the estimation of photometric redshifts. Stacking techniques can feed the photometric redshift estimate, as output by a base algorithm, back into the same algorithm as an additional input feature in a subsequent learning round. We shown how all tested base algorithms benefit from at least one additional stackin...
